DALLAS -- Guard Rodrigue Beaubois underwent surgery to repair the fractured second metacarpal in his left hand, the Mavericks announced Wednesday night.

No official timetable has been set for Beaubois' return, but the odds of him playing again this season are extremely slim.

Beaubois, a fourth-year guard whose future seemed so bright after a rookie season that featured several flashes of brilliance, was a fringe rotation player this season. He averaged career lows in points (4.0), rebounds (1.3), field goal percentage (.369), 3-point percentage (.292) and minutes while playing in 45 games this season, although he played well in two wins the week before he was injured.

Beaubois will be a free agent this summer, meaning he might have played his last game for the Mavs.

“I feel bad for the kid,” Dirk Nowitzki said after Beaubois broke his hand Sunday. “It’s just sad. Just so many injuries. He’s been here for four years and has missed a lot of action. … It’s tough. We feel bad for him. But he’s a good kid.

“He’ll stick around. The good thing is when you break your hand, you can still work out and run and stay in decent shape, because this is obviously a big summer for him. He’s a free agent and he obviously wants to stay in the league and have a long career. Hopefully he can get healthy and we’ll see where he lands.”
